If you try doing a search for something like "fixed flash" using the sticky post at the top of the thread list, you'll find quite a few previous threads on this area. For example:

I'm not talking about IAP, want the code in C LPCXPRESSO set a fixed value in memory Fash, set the value 0x01 at address 0x7F00.
In the pic (microchip) I wore org0x7F00 DE 0x01, want to know what is the equivalent command in LPCXPRESSO.

MCU: LPC1114.

Which MCU?
Flash is NOT eeprom!
Flash has a limited number of write cycles.
Flash has to be erased in blocks.

Look at the IAP commands for your MCU. The user manual is your friend :rolleyes:

Anyone know?
I reserve the memory and put the command below but does not record the flash.

__attribute__((section (".mem2"))) const unsigned char byteTest = 'w';
